Analysis of DNA polymorphism in wild populations of herb-Paris (Paris quadrifolia L., Trilliaceae) from Lithuania and Norway.
(Journal article; Peer reviewed, 2006)Analysis of random amplified polymorphic DNA (RAPD) was used to determine genetic diversity within the populations of herb-Paris plant from Lithuania and Norway. RAPD analyses have shown 21.9 ± 5.2% of polymorphic loci in ... -
Detection of tick-borne pathogens by molecular methods
(Journal article; Peer reviewed, 2008)The use of molecular methods such as species-specific PCR, Multiplex-PCR, RT-PCR, reverse line blot hybridisation in investigations of tick-borne pathogens allowed to detect and identify the causative agents of Lyme ... -
Diversity of thermophilic Campylobacter isolated from slaughter pigs in Norway
(Journal article; Peer reviewed, 2008)Out of 100 faecal swab samples, 88 thermophilic Campylobacter representing ten herds were isolated. The species were identified by biotyping and multiplex polymerase chain reaction (PCR). Of the isolates, 86 (97.7%) were ... -
Diversity of thermophilic Campylobacter isolated from the Bø River, Southeast Norway
(Journal article; Peer reviewed, 2009)Out of 125 samples we isolated 45 thermophilic Campylobacter spp. from Bø River by filtration followed by growth on selective agar plates. The species were identified by biotyping, multiplex PCR and riboprinting. C. jejuni ... -
Genetic structure in an expanding cervid population after population reduction
(Journal article; Peer reviewed, 2009)The Norwegian red deer population (Cervus elaphus) was from the mid eighteenth to the early twentieth century drastically reduced in size and distribution but has the last century expanded both demographically and spatially. ... -
Genetic variation and structure in Norwegian red deer
(Doctoral thesis; Peer reviewed, 2008-07)In all species the abundance and distribution of populations vary through time and space, but recently major changes in the size and range of many populations have been observed. Population contractions and founder events ... -
Genetic variation of ticks (Ixodes ricinus L.) in the Lithuanian and Norwegian populations
(Journal article; Peer reviewed, 2006)RAPD markers were used to measure the genetic diversity of 119 individuals of Ixodes ricinus collected from Lithuania and Norway. The samples were analysed within and also between the populations. We analysed 74 loci in ... -
Mitochondrial phylogeography of the Eurasian beaver Castor fiber L.
(Journal article; Peer reviewed, 2005)Nucleotide variation in an approximately 490 bp fragment of the mitochondrial DNA control region (mtDNA CR) was used to describe the genetic variation and phylogeographical pattern in the Eurasian beaver ( Castor fiber ) ... -
Prevalence of Anaplasma phagocytophilum and Babesia divergens in Ixodes ricinus ticks from Lithuania and Norway
(Journal article; Peer reviewed, 2008)We detected Anaplasma phagocytophilum and Babesia divergens in Ixodes ricinus ticks collected from different locations in Lithuania and Norway by using the Taq Man based real-time PCR method. The msp2 gene of A. phagocytophilum ... -
Similarity of Campylobacter lari among human, animal, and water isolates in Norway
(Journal article; Peer reviewed, 2008)A total of 49 isolates of Campylobacter lari from human, poultry, ducks, pigs, and water were genetically characterized. The species were identified by biotyping and multiplex polymerase chain reaction (PCR). Automatic ... -
The prevalence and distribution of Borrelia burgdorferi sensu lato in host seeking Ixodes ricinus ticks in Lithuania
(Journal article; Peer reviewed, 2006)A total of 1559 unfed Ixodes ricinus (L., 1758) ticks were collected from the vegetation by flagging in 18 locations of Lithuania. The ticks were tested individually for the presence of spirochetes using polymerase chain ... -
The prevalence of Anaplasma phagocytophilum in host-seeking Ixodes ricinus ticks in Norway
